Front derailluer shifting problems

graememacd

I'm having problems shifting into the big ring with my SLX double front derailluer using Deore shifters. It is really hard to push the shifter into place. I have attached a couple of pictures,any ideas let me know

Youve got the cable on the wrong side of the anchor bolt it should be running round from the outside of the mech, if you undo it and switch it it should shift fine

Just done that and it does move the derailluer more easily however the shifter now doesn't get anywhere near the position where it clicks into place

Check the limit screws are set correctly if the high limit is to far in it wont allow the shifter to click in

What did you change?

I think the limit screws are ok, I am wondering if the deore shifters are set up for 10 speed as I know the XT ones have a switch at the bottom to change between double and triple. No such switch on deore

I changed how the cable clamps to the derailluer. In the second photo it now comes down to the left of the allen bolt and round underneath it sticking out to the right

No difference ten to nine speed and that wouldn't make it hard to shift, sounds very like you are pulling it onto the limit screw and that's making is harder, even if the limit screw is set right you could have changed the cable tension when it was apart and thus it's not getting into the next gear at the shifter before hitting the limit screw, back off the limit screw a bit and I bet you fix it.

I'll have a play with it this afternoon and see if it is that. Hopefully that'll sort it. I'll let you know!

If in doubt, start all over again, read the guide on Parktool.com

I meant what did you do just before it became a problem. Presumably at some point it worked?

I didn't change anything, it was a bike i built up earlier this year and it has always been like this. I haven't ridden it that much that's why it hasn't really been a problem but as it gets cold and slippy out there i tend to leave the road bike in the garage and head out on the mountain bike. it would change into the big ring but it would take a lot of force to get it there

Then this

99% it's the stop by using a lot of force you are stretching/ bending everything until the shifter engages into the higher gear.

Solved! The limit screws were fine however the shifter has 3 positions and I had the double chainset set to use the first two positions on the shifter. I changed it so the smaller chain ring was position 2 and the bigger ring at position 3. All sorted and I can't believe I didn't spot this before! Obviously used to building double chainset Road bikes...
Thanks for the replies all

cooldad

So was just bad set up which has been fixed by adjusting correctly. It makes no difference which click you start from.

The Rookie

Doesn't make one iota of difference which way round it was, but by doing that you will have had to set the cable tension again won't you, bad set up and the stop screw in the way.

graememacd

Clearly it does make a difference! I tried several things to get it working before, it shifts exactly how it should now

I ran into the same issue when setting up my 2 x 9. I googled and found that first to second draws 7mm of cable, while 2nd to 3rd draws 11mm cable.

That would definitely explain it then, thanks

I'll believe that when I see the reference.

The Rookie

I've run mine both way rounds, no problem, even if it did draw more cable it would still move the mech unless something stopped it, oh like the stop.

graememacd

Clearly not as the stops were already set, plus the mech did move. I'm not sure you understood the problem. Thanks for your suggestions anyway

The Rookie

You aren't getting it are you, the stop may have been in the right place but the cable was too tight pulling it into the stop before it engaged the ratchet at the shifter, suggest you avail yourself of an understanding of how it works before telling us we are wrong.

Just undid a Deore left hand shifter, same radius spool all the way round, so same app able pull for both clicks.

graememacd

Not really sure what you're trying to achieve here. The problem is fixed. Give it a rest

The Rookie

Trying to educate you.....after all you couldn't even route the cable right at the start.....

graememacd

Grow up and go and bother some one else. Merry Christmas

The Rookie

I am grown up, just you aren't grown up enough to
1/ recognise it
2/ be gracious to people who have spent their time trying to help you
3/ acknowledge that people are trying to educate you so you don't have issues again in the future

Merry Christmas to you as well.
